Owing in the index file of audio frequency and video, record has multiple file fragmentations of described audio frequency and video, each fileBurst all includes the partial information of audio frequency and video, if audio frequency and video to be played out by client, it is necessary toThe information of the file fragmentation according to audio frequency and video downloads corresponding audio frequency and video from the corresponding network address.ExistingIn technology, client needs to resolve all files burst in the index file of audio frequency and video, will solveThe information of All Files burst that analysis obtains is saved in this locality, then according to the information of file fragmentation sequentially fromDownload audio frequency and video on the corresponding network address and play out.Owing to the index file of audio frequency and video comprising relativelyMany file fragmentations, therefore resolving substantial amounts of file fragmentation before playing audio-video needs consuming longerTime, cause audio frequency and video acts that to broadcast speed the slowest.In order to avoid the problems referred to above, the embodiment of the present invention needsPerform step 102 determine from file fragmentation for the file fragmentation broadcast.Described for acting the file broadcastBurst is that sub-fraction in audio frequency and video index file broadcasts relevant file fragmentation with rising, described with broadcastThere is rising of the Central Shanxi Plain to broadcast situation, both included the playing audio-video that starts anew, also included directly dragging to certain togetherBroadcast and a little commence play out audio frequency and video.
103, the file fragmentation being used for broadcasting is resolved, obtain for acting the burst information broadcast.
When determining in a step 102 after acting the file fragmentation broadcast, it is necessary to being used for the literary composition broadcastPart burst resolves, and obtains for acting the burst information broadcast.Owing to being used for the file fragmentation quantity broadcastLess, therefore resolve the most less of these file fragmentations, and believe according to the burst of these file fragmentationsBreath ensure that rising of audio frequency and video is broadcast.
104, download and playing audio-video according to the burst information being used for broadcasting.
When having obtained in step 103 after acting the burst information broadcast, client just can according toThe burst information broadcast in is downloaded and playing audio-video.Owing to resolving the time-consuming of the file fragmentation that has been used for broadcastingShorter, the burst information that therefore client can obtain according to parsing faster commences play out audio frequency and video, fromAnd improve rising of audio frequency and video and broadcast speed.
What the embodiment of the present invention provided acts the processing method broadcasting speed, it is possible to obtained audio frequency and video by clientIndex file, obtains the file fragmentation of described audio frequency and video from described index file；From described file fragmentationMiddle determine for acting the file fragmentation broadcast；Resolve for a file fragmentation broadcast described, usedThe burst information broadcast in；Download and play described audio frequency and video according to described for a burst information broadcast.And in the prior art, client needs all to resolve each file fragmentation in audio frequency and video index file,After obtaining the download address that each file fragmentation is corresponding, just can carry out corresponding audio frequency and video sheet according to download addressThe download of section and broadcasting, thus cause audio frequency and video act that to broadcast speed the slowest.With defect phase of the prior artRatio, the embodiment of the present invention can resolve partial document burst for audio frequency and video from the index file of audio frequency and videoRise broadcast, thus shorten resolve index file time, and then can improve audio frequency and video rise broadcast speed.
In order to preferably the method shown in above-mentioned Fig. 1 be understood, thin as to above-mentioned embodimentChanging and extension, the embodiment of the present invention will be described in detail for each step in Fig. 1.
Before client terminal playing audio frequency and video, need to send data acquisition request to server, be used for obtainingThe index file of described audio frequency and video, and the file of described audio frequency and video is obtained according to the index of described index fileBurst.Such as, client can send data acquisition request to server in embodiments of the present invention, usesIn the M3U8 file of acquisition audio frequency and video, described M3U8 file is to have recorded an index text-only file,Wherein containing the ts file of audio frequency and video i.e. each file fragmentation of audio frequency and video, each file described dividesSheet constitutes complete audio frequency and video.Client is after the M3U8 file getting audio frequency and video, it is possible toEach ts file of audio frequency and video is obtained from M3U8 file.
After client gets each file fragmentation of audio frequency and video, need with client in prior artResolve each file fragmentation and the result of parsing is carried out the mode difference of local preservation, the embodiment of the present inventionIn order to reduce resolve audio frequency and video index file time, need determine from the file fragmentation of audio frequency and video forAct the file fragmentation broadcast.Concrete, can determine for rising according to the file fragmentation number of described audio frequency and videoThe file fragmentation broadcast.The number for acting the file fragmentation broadcast determined is necessarily less than the literary composition of described audio frequency and videoTotal number of part burst, the number of file fragmentation being used in theory broadcasting is the fewest, carries out the time resolvedThe shortest, thus ensure audio frequency and video act that to broadcast speed the fastest.But, the file fragmentation being used for broadcastingNumber is not the fewest more good, if the file fragmentation being used for broadcasting is very few, then when being used for the file fragmentation broadcastFile fragmentation follow-up after being played the most is not parsed, then audio and video playing can be caused to interrupt, because ofThis, need to determine in a default scope by the number of file fragmentation being used for broadcasting, described defaultScope can determine according to audio frequency and video downloading rate, when audio frequency and video downloading rate is fast, then increase and be used forThe number of the file fragmentation broadcast；When audio frequency and video downloading rate is slow, then reduce the file fragmentation that has been used for broadcastingNumber.By the way, under conditions of less than the All Files burst number of audio frequency and video, eitherHeighten and still turn down the number for acting the file fragmentation broadcast for the number acting the file fragmentation broadcast, as long asDetermine ensure that for acting the number of the file fragmentation broadcast normal the rising of audio frequency and video is broadcast, and follow-up literary compositionThe parsing of part burst can be supplied client in time and be carried out audio frequency and video and download.
